Abstract

In accordance with one embodiment of the present invention, a specimen surface treatment system is provided comprising a vacuum chamber, a plasma chamber, a specimen holder port, and a specimen shield. The plasma chamber comprises an RF antenna positioned within the vacuum chamber so as to give rise to a capacitively coupled glow discharge plasma in a process gas contained within the vacuum chamber. The specimen shield is positioned within the vacuum chamber so as to define a preferred grounding path between the RF antenna and the specimen shield for ions generated in the plasma. The grounding path is preferred relative to a grounding path defined between the RF antenna and the specimen position. Additional embodiments are disclosed.
